5.3.4 Read SERVOPACK Parameter (PRM_RD)
The PRM_RD command reads the setting of the SERVOPACK parameter with the specified
parameter number and parameter size and stores the parameter number in Auxiliary Servo User
Constant Number (monitoring parameter IW††37) and the setting in the Auxiliary Servo User
Constant (monitoring parameter IL††3A).
The source read data is in the SERVOPACK's RAM.
This command will end with a Command Error End if it is executed with a communication method
other than MECHATROLINK-II (32 byte).
